Mahler's theorem for continuous functions on the $p$-adic integers (Theorem)
Theorem (Mahler)   Let $f$ be a continuous function on the $p$ -adic integers taking values in some finite extension $K$ of $\mathbb{Q}_p$ , and for each $n\in\mathbb{N}$ , put $a_n=\sum_{i=0}^n(-1)^{n-i}\tbinom{n}{i}f(i)$ . Then $a_n\rightarrow 0$ as $n\rightarrow\infty$ , the series $\sum_{n=0}^\infty a_n\tbinom{\cdot}{n}$ converges uniformly to $f$ on $\mathbb{Z}_p$ , and $\norm{f}_\infty=\sup_{n\geq 0}\abs{a_n}_p$ , where $\norm{\cdot}_\infty$ denotes the sup norm.
